Dive Gear/Immersion Suits
Pendana carries with her a decent air tank, regulator and Aqua lung vest. This will provide about 80 minutes of air which should prove long enough the untangle the most persistent of things that may in the highly unlikely event get wrapped around Pendana's shaft or propellor.
Pendana also carries a number of immersion suits which if required would extend human life for a number of hours if an abandon ship was required. Immersion suits are one thing nobody ever wants to have to use, unless of course it is for practice purposes only.
